TECHNICAL NOTE
ALUMINUM ELECTROLYTIC CAPACITORS
WITH CONDUCTIVE POLYMER SOLID ELECTROLYTE
?
? During cleaning, control the cleaning solution
against contamination.
6. Fixing adhesives and coating materials.
? Do not use halogenated fixatives and coatings.
? Before using a fixative or coating, remove flux
residues and contaminants from between the PCB
and the sealing section of capacitors.
? Dry the cleaning solution before using the adhesive
or coating.
? Do not cover up all the sealing sections (terminal
side) of capacitors with the adhesive or coating.
? Heat curing conditions of fixative and coating.
Other Cautions
1. Do not directly touch the terminals of solid con-
ductive polymer aluminum electrolytic capacitors.
Failure to do so can cause electric shock or burns.
Before use, allow capacitors to discharge through a
1k Ω resistor (with a sufficient margin to the heat
generation capacity) as needed.
2. Do not short-circuit between the terminals of
the solid conductive polymer aluminum electrolytic
capacitors with electric conductor. Do not subject
capacitors to conductive solutions such as acid
and alkaline water solutions.
3. Periodic inspection should be performed on the
capacitors for the industrial equipment application.
Check the following checkpoints.
? Visual inspection to check for significant defects.
? Electrical performance: leakage current, rated
capacitance, tangent of loss angle, ESR, and items
? During delivery, capacitors are stored in airtight
moistureproof bags to ensure satisfactory soldering.
Once the bag is opened right before mounting, it is
better to use up the capacitors. If some are unavoid-
ably left over, return them to the moistureproof bag,
and seal the opening hermetically.
? Solid conductive polymer aluminum electrolytic
capacitors may have increased leakage current
when unused or stored for a long time after mounted
on equipment. This phenomenon often occurs at
high ambient temperatures; however, leakage
current will decrease through voltage treatment. If
leakage current still increases after a lapse of more
than one year at ambient temperature (shorter time
at high temperatures), treat with voltage as needed.
In design of equipment, consider the effect of
increase in initial current, and install protective
circuits as needed.
Please check that recommended voltage treatment
conditions are provided for each series.
? Do not store capacitors in an environment directly
exposed to water, saltwater spray, oil spill or
condensation.
? Do not store capacitors in an environment filled with
toxic gas such as hydrogen sulfide, sulfurous acid,
nitrous acid, chlorine, ammonia, etc.
? Do not store capacitors in a place exposed to ozone,
ultraviolet rays, or radiation.
6. Please take the following actions when
disposing of solid conductive polymer aluminum
electrolytic capacitors.
? Entrust to specialists of industrial waste treatment for
incineration.
specified in the catalog or delivery specification.
7. Others
4. Be careful of the following cases of emergency.
? In case of a short during use of capacitors in sets,
producing gas, turn off the main power of the set or
unplug the power cord from the outlet.
? In case of a short, producing gas, it may take a few
seconds to a few minutes depending on the
conditions. Therefore, ensure that the protective circuit
of the power supply works during this time.
? If the gas gets in your eyes, rinse them immediately.
? Before using capacitors, check the details of this
delivery specification and catalog as well as the
following.
Technical Report of Japan Electronics and Information
Technology Industries Association
EIAJ RCR-2367B
Guideline of notabilia for fixed aluminum electrolytic
capacitors for use in electronic equipment
Gargle if the gas is inhaled.
? Do not lick the electrolyte of capacitors. When the
electrolyte gets on your skin, wash it off with soap
immediately.
5. Storage Conditions.
? Do not store at high temperature and high humidity.
Store at a temperature of 5 to 35°C and a relative
humidity of less than 75%, keeping free from direct
sunlight.
